Abstract

In view of the following problems: the backward technology in remote meter reading, the poor interoperability of communication protocol and the high cost for network operation, the author has proposed a two-layer network construction based on GSM and ZIGBEE and designed the communication protocol of remote meter reading system with consideration of the data characteristics of meter reading system. And then, to ensure the reliability of communication links, the serial communication program is designed by calling, answering and then communicating after repeated experiments. In the end, the designed system is tested under experimental conditions, and the results show that the system had many advantages, such as high reliability, low cost, simple networking, high reliability for communication data and moderate speed of meter reading, and satisfied the design requirements basically.
